  • the RPD is defined as the difference of RP between two time instants t 1 and t 2 , i.e., ⁇ ( t 1 ) - ⁇ ( t 2 ) .
  • the RPD of a transmitter branch typically comprises a power-dependent term and a time-dependent term.
  • the power-dependent term depends on the transmit power, whereas the time-dependent term varies with time. From the viewpoint of modelling, the power-dependent term can be given as a function of the current transmit power, whereas the time-dependent term can be given as an additive random process.
  • the power-dependent RPD mainly comes from the power/configuration mode switching by which each transmitter branch switches the gain/bias state.
  • the potential sources of the power-dependent RPD can be summarized as follows.
  • the RPD between the measurement and the relevant precoding is of interest.
  • SRS is a natural choice for precoder selection
  • the RPD may lead to non-optimal precoder selection, even when the wireless channel is perfectly known to the eNB. This may result in non-trivial performance loss, since the precoder selection typically relies on the phase information of the transmitter branches.
  • the time frame of interest is about a few, or a few tens of, subframes. It depends on the processing time, due to for example measurement and precoder selection, and the SRS periodicity. For example, if the processing time is 8 msec and the period of SRS transmission is 10 msec, a minimum of 8 msec and a maximum of 17 msec should be assumed as the time frame. Given such a time frame, the power-dependent term has a larger impact on RPD than the time-dependent term and thus focus is on the power-dependent term, i.e., how to cope with it, in this disclosure.
  • the RP is given a function of the current transmit power.
  • Figure 6 shows an example of the relationship between transmit power and RP. It is shown that RP changes abruptly across a few transmit power levels - referred to as switching points hereafter.

  • the operation mode above P MH is called high-power mode (HPM).
  • LPM low-power mode
  • MLM mid-power mode
  • HPM high-power mode
  • Each mode has its own bias state and the phase of a bias state is not necessarily equal to those of other bias states. This justifies the aforementioned RP change across the switching points.
  • the transmit power change causes the mode switching of a transmitter, comprised in the user equipment 120, and the mode switching between SRS and PUSCH in turn causes the RPD.
  • Figure 7 shows a typical case where PUSCH and SRS are transmitted with different power levels.
  • the first SRS symbol, SRS 1 is transmitted at time instant t S,1 with power level Ps and the second SRS symbols, SRS 2 , is transmitted at time instant t S,2 with power level Ps.
  • One of the PUSCH symbols, PUSCH is transmitted in between, i.e., at time instant t P with power level P P . Since the PUSCH power level is different from the SRS power level, RPD may occur between SRS and PUSCH.
  • the two SRS symbols experience the same phase shift, since they are assumed to have the same power level. It is important to note that Ds and D P become different when Ps and P P are on different sides of a switching point, in other words, SRS 1 (or SRS 2 ) and PUSCH operate in different modes, as exemplified in Figure 8 . This causes RPD between SRS and PUSCH.

This may also be called as the vendor declaration or declared information.
  • the vendor-specific switching point information may vary with the model and release of UE. The vendor-specific switching point information may also depend upon the frequency bands, RATs, number of supported RATs, power class of the UE for each RAT etc.
  • the radio network node 110 e.g. eNode B, BS, Node B, RNC etc, can therefore store the declared information related to the switching point of the UE for different types, classes, models, release etc of UEs. This information can therefore be maintained in the radio network node 110 in the form of a look up table or a data base and it can be used for determining the switching point of a particular UE when it is served by the radio network node 110.

  • PHR or aka PH is the difference between the UE maximum power and the UE transmitted power expressed in dB scale.
  • the eNB can measure the RP of the UE. For example, the consecutive SRS transmissions enable the eNB to measure the RP, when the fading channel remains static between the SRS transmissions.
  • the PHR indicates that the SRS transmit power changes between the SRS transmissions, it is possible to find the power level and phase value of the switching point.
  • the radio network node 110 may determine the mode switching information of a UE and use the same information for other similar UEs i.e. UEs of the same type in terms of performance, model, power class, supported bands, supported RATs etc. Therefore the switching point information can be determined by the radio network node 110 for certain number of UEs and can be stored in the node and used for the same and similar types of the UEs in the future e.g. for scheduling etc.
  • the radio network node 110 collects the mode switching information from the UEs of the same type. This helps to improve the accuracy of the mode switching information. For example, when one UE has the SRS transmit power crossing one switching point and the other UE of the same type has the SRS transmit power crossing another switching point, it is possible to obtain the information on these two switching points for the UEs of the same type. In other words, by collecting the measurements from the UEs of the same type that operate in different modes, it is possible to obtain the complete mode switching information of UEs of the type. This may be useful when the SRS transmit power does not change so rapidly and it is practically impossible to obtain the complete mode switching information from the measurement of a single UE.
  • the radio network node 110 may obtain the mode switching information by scanning the transmit power range of interest and measure the corresponding RP. For example, the eNB ramps up the SRS transmit power monotonically and measures the corresponding RP. If the SRS transmit power ranges from the minimum transmit power to the maximum transmit power, it is possible to capture the complete switching point information. Alternatively, the eNB may ramp down the SRS transmit power monotonically and measures the corresponding RP i.e. from maximum to minimum UE transmit power. The radio network node 110 may apply this procedure when there is low uplink traffic in the cell and/or when UE is not transmitting any data. In this way the network can more accurately determine the mode switching information by assigning adequate resources.
  • the SRS transmit power is determined by parameters such as the SRS bandwidth and the desired target SNR value etc. For example, by changing the SRS bandwidth, it is possible to fulfill the power ramp up/down. Note that such power ramp up/down can be fulfilled on a per subframe basis, if aperiodic SRS is used.
  • the power step of the aforementioned power ramp up/down determines the amount of the SRS resource.
  • the radio network node 110 can select the power step based on the declared information. For example, if the radio network node 110 can figure out the approximated power level difference between two switching points, it can adjust the power step accordingly.
  • the radio network node 110 may determine the mode switching information of a UE by scanning and use the same information for other similar UEs i.e. UEs of the same type in terms of performance, model, power class, supported bands, supported RATs etc. Therefore the switching point information can be determined by the radio network node 110 for certain number of UEs based on scanning and can be stored in the node and used for the same and similar types of the UEs in future e.g. for scheduling etc.
  • the radio network node 110 collects the mode switching information from the UEs of the same type. This helps to improve the accuracy of the mode switching information. For example, when the radio network node 110 scans the first half of the transmit power range for one UE and scans the second half of the transmit power range for another UE of the same type, it is possible to obtain the information on these transmit power ranges for the UEs of the same type. In other words, by collecting the power ramp up/down from the UEs of the same type that operate in different modes, it is possible to obtain the complete mode switching information of UEs of the type. This may be useful when the SRS resource dedicated to each UE is not enough to scan the whole transmit power range and it is practically impossible to obtain the complete mode switching information from the power ramp up/down of a single UE.
  • the radio network node 110 may want to scan the transmit power range for each UE, even when the mode switching information is available from other UEs of the same type.
  • the mode switching information obtained from other UEs of the same type can be used as initial information, for example, to optimize the power step for the power ramp up/down of a UE of the same type.
  • the radio network node 110 obtains the mode switching information based on explicit indication from the UE.
  • the mode switching information can be acquired by the radio network node 110 from the UE which may contain the pre-determined information stored in the UE, Alternatively when the radio network node 110 requests the mode switching information or when the UE has to send the mode switching information to the radio network node 110 then the UE performs certain radio measurement to first obtain the mode switching information.
  • the UE may perform measurements such as UL transmit power to determine the mode switching information.
  • Such a network-triggered UE measurement and report may help reduce UE power consumption, for example, when the radio network node 110 can obtain the mode switching information from the UEs of the same type and wants to reuse the information for other UEs of the same type.
  • the UE may signal the mode switching information which may be specific for different RATs, bands, UE power class etc. For example if UE supports LTE and HSPA, then it may report mode switching information for each RAT. Alternatively it may report one common mode switching information for all RATs.
  • the UE may send the mode switching information to the radio network node 110 in any of the following manner:
  • the UE may report its mode switching information during one or more of the following occasions:
  • the radio network node 110 receiving the mode switching information from a UE may store the received information and may use this also for similar UEs which don't signal their own mode switching information.
  • the term similar UE implies the UEs of the same type in terms of performance, model, power class, supported bands, supported RATs etc.
  • the similarity between UEs can be determined using the mechanism described earlier, for example by the method of obtaining information through pre-defined information.
  • the similar UE types are expected to have the same mode switching capability. This approach also reduces the signaling overheads since all UEs don't have to signal their mode switching information to the radio network node 110.
  • the radio network node 110 may obtain the mode switching information of a UE for certain RAT, e.g. LTE, using any of the methods disclosed above. Let us call this RAT as reference RAT. The radio network node 110 then observes the radio transmitter performance of that UE when it operates on another RAT. Example of radio transmitter performance is accuracy or tolerance of the UE maximum output power. If the performance on the two RATs are the same or similar then the network may assume that the same mode switching information is applicable on both RATs. For example only LTE part of the multi-RAT (HSPA/LTE) UE may explicitly indicate its mode switching information to the radio network node 110. However the HSPA and LTE may use a common radio and therefore mode switching information may be the same for both RATs.
  • LTE part of the multi-RAT (HSPA/LTE) UE may explicitly indicate its mode switching information to the radio network node 110. However the HSPA and LTE may use a common radio and therefore mode switching information may be the same for both RATs.
  • the radio network node 110 upon determining the UE mode switching information adapts the UL transmission of the UE to improve the UL performance e.g. improving UL reception quality at the radio network node 110, UL detection performance at the radio network node 110 etc.
  • all UEs may not have multi-stage PA, e.g., envelope tracking PA, and therefore there is no mode switching for this UE when UE transmits signals in the uplink.
  • the radio network node 110 therefore adapts the UL transmission only of those UEs which does mode switching and whose mode switching information is available.
  • the radio network node 110 may apply one or combinations of these adaptations.
  • the serving radio network node serving the UE typically selects the UL PC parameters for this UE based on UL received signal quality. However according to this embodiment the radio network node 110 also takes into account the mode switching information of the UE when selecting the UL PC parameters.
  • the adaptation of UL transmission includes the adaptation of the power control related parameters configured by the radio network node 110, e.g. the TPC commands, the resource allocation, such as the SRS or PUSCH bandwidth, the SRS power offset etc.
  • the parameter related to resource allocation can be UL grant or aka UL scheduling grant or UL assigned resource etc.
  • the parameters related to SRS configuration can be adapted on a per subframe basis, if aperiodic SRS is configured with different parameters.
  • These UL PC parameters which can be adapted are signaled to the UE and can be updated by the network serving the UE. For example, given the power levels of the switching points, it is possible for the network to adjust one or more parameters related to the UL PC. This in turn can enable the UE to adapt the SRS or PUSCH transmit power such that there is no mode switching between SRS and PUSCH. Obviously, this may help to reduce the RPD. In addition, given the phase values of the switching points, further optimization of RPD is possible. Note that any parameters used as the input argument of the power control formula can be involved in the adaptation of the UL transmission.
  • the UE determines the mode switching information related to its multi-stage radio implementation for the UL transmission and autonomously adapts its UL transmission in order to avoid the UL transmitted signal causing higher RPD. This in turn will enable the serving node to more easily receive and decode the UL signal transmitted by the UE.
